Title: Axially spreading brake of the segmental brake pad type
IPC: F16D65/14
Filed: 1963-02-28
Abstract: 1,022,974. Disc brakes. H. KLANE. Feb. 28, 1963 [Feb. 28, 1962; March 15, 1962], No. 8028/63. Headings F2E and F2F. A disc brake has a rotatable brake housing with radial braking surfaces and one or more braking units arranged in the peripheral direction comprising two axial displaceable brake pads and two spacing devices arranged between the pads and which pivot in opposite directions around axes parallel to that of the brake housing when the brake pads are applied. In the embodiment shown, the pads 15, 16 carrying lateral friction linings 17-18 and 19-20 are attached to presser rings 21, 22 and are spread apart to contact the radial sides of the housing 4 by rollers 25, 26 riding up inclined raceways provided in the rings 21, 22 and in medial rings 27, 28 on rotation of the latter. The medial rings are rotatable on rollers 24, disposed about the spindles 23 carried by the presser rings in opposite directions by the pneumatically or hydraulically operated piston-cylinder device 9, 11, 12. The presser rings 21, 22 are provided with projections 21a, 22a which engage the projecting extensions 10 of the cylinder 9 to transfer the braking torque thereto. The pads are released by a spring 30a. The brake unit may be removed radially outwards through an aperture in the housing after the securing screws 32 have been released. A mechanical actuating device for the brake is provided by a lever 35 that is adjustably pivoted at 36 and one end of which engages a member 29 fitted to one medial ring and the other end of which is connected to a cable 41. Only the friction linings 18, 20 thus serve for mechanical braking purposes. However, a further lever which actuates the other medial ring may be actuated by a Bowden cable sheath. In another embodiment, Fig. 7 (not shown), wherein the brake casing is closed inwardly and the brake cylinder is disposed outside the outer surface of the casing, rollers 65, 66 which ride in inclined raceways are disposed between one side of the medial rings 63, 64 and the presser rings 61, 62 whereas rollers 67, 68 are disposed between the other side of the medial rings and spherical projections 69, 70 on the presser rings. This allows a certain obliquity of the brake pads to take place. The raceways of the first embodiment may be given a spherical shape so that the pads may assume an oblique position.
Patent GB-751035-A (GB)
Title: Improvements in and relating to the condensation of dialkyl succinates
Inventor: LENEL PAUL OTTO
Filed: 1954-03-19
Abstract: A process for the production of di-alkali metal derivatives of dialkyl cyclohexa-1,4-diene - 2,5 - diol - 1,4 - dicarboxylates comprises the step of contacting a dialkyl succinate with an alkali metal alkoxide in the presence of an organic diluent, which is a liquid under the reaction conditions, the said diluent being an ether having a boiling-point of at least 90 DEG  C.  Suitable succinates are dimethyl and diethyl succinates.  Suitable alkoxides are methoxides and ethoxides particularly those of sodium.  A lower aliphatic alcohol may be employed as solvent for the alkoxide, conveniently corresponding to the alkoxide. Suitable ethers are di-n-propyl, di-n-butyl, di-isobutyl and di-sec.-butyl ethers and higher ethers, ethers containing two oxygen atoms, e.g. ethylene-glycol dimethyl ether and dioxan. When dioxan is employed as diluent in the preparation of the di-sodium derivative of the dimethyl ester of cyclohexa - 1,4 - diene - 2,5 - diol - 1,4 - dicarboxylic acid the desired product may be filtered off and the dioxan and unchanged ester starting material recycled to the condensation stage.  The free diols may be obtained by acidification of the di-alkali metal derivatives.  In examples: the di-sodium derivative of cyclohexa-1,4-diene - 2,5 - diol - 1,4 - dicarboxylate, which is converted to the free diol by acidification with hydrochloric acid, is obtained by heating dimethyl succinate, sodium methoxide, dioxan and methanol under nitrogen (1); di-ethyl cyclohexa-1,4-diene-2,5-diol-1,4-dicarboxylate is similarly obtained using di-ethyl succinate as starting material (2); dimethyl cyclohexa-1,4-diene - 2,5 - diol - 1,4 - dicarboxylate is obtained on adding a mixture of dimethyl succinate and dioxan to sodium-tert.-butoxide, adding additional dioxan and heating, cooling, filtering off the solid produced and acidifying with dilute aqueous hydrochloric acid (3).  Diethyl cyclohexa-1,4-diene-2,5-diol-1,4-dicarboxylate is stated to be similarly prepared using diethyl succinate instead of dimethyl succinate.  Specification 742,949 is referred to.

Title: Improvements relating to electronic control systems
IPC: B23K11/24
Filed: 1944-04-29
Abstract: 588,365. Control systems for resistance welding. FERRANTI, Ltd., and BUCHANAN, W. H. April 29, 1944, No. 8094. [Class 38 (iv)] Switching control.-In an electric-control system for supplying spaced pulses of electrical energy from a common source to one or more of a series of load devices, such as spot welders, each of which is associated with switching means to determine the instant of commencement of the supply of pulses thereto, a gridcontrolled relay tube 25 and a similar control tube'2, which may be of the kind known as Thyratrons are associated to feed spaced pulses to feeder lines 40, 401, and a Thyratron 16 delivers voltage pulses to pilot lines 38, 38<1>, the arrangement being such that the operation of a pedal switch 47 at any one of the welding stations A causes voltage pulse to be applied to the grid 42 of a Thyratron 43 at the station, thereby energizing a relay coil 50 in the anode circuit and closing the contacts 53, 54 in the primary circuit of a welding transformer 56, connected across the feeder lines 40, 40<1>. In accordance with the control exercised thereon the Thyratron 25 produces spaced pulses, each containing one or more uni-directional halfcycles of energy. Alternatively, by employing two similar Thyratrons 25, arranged back-toback, pulses each containing one or more complete cycles, or one or more complete cycles and one half-cycle are obtained. The Thyratron 2 is associated with a condenser 19 to generate saw-tooth oscillations which are fed through the secondary winding of a peaked wave transformer 21 to the grid of Thyratron 25, the anode of which is connected to one line of an A.C. supply 10 and the cathode 41 to one of the feeder lines 40<1>. The primary winding of transformer 21 is connected to the supply 10,through a phase shifter 23, and the control grid of Thyratron 25 is biassed so that only a desired number of peaks in each cycle of the resultant peaked voltage wave form applied to the grid permit Thyratron 25 to conduct when its anode is positive. The anode 31 of Thyratron 16 is connected through a resistance 32 to a positive D.C. source and the grid 15 is biassed negatively to prevent conduction until Thyratron 2 becomes conducting, whereupon a connection including a condenser 14 causes the grid 15 to become increasingly positive so that Thyratron 16 becomes conducting and current flows through the primary winding 35 of a cathodeload transformer which has its secondary winding 37 connected across the pilot lines 38, 38<1>. The timing of conduction of Thyratron 2 is controlled by applying a peaked wave voltage to its control grid over the secondary winding of a peaked wave transformer 9, which has its primary winding connected across a phase shifter 11. The anode circuit of the Thyratron 43 at the welding station is critically damped by a resistance 52 in parallel with a condenser 51 and, together in series with the inductive relay winding 50.

Abstract: 585,868. Optical-projection apparatus. STANDARD TELEPHONES & CABLES, Ltd., McWHIRTER, E. M. S., and DUNN, R. H. May 3, 1944, No. 8334. [Class 97 (i)] A projector combined with a typewriter or other printing machine to project an image of the matter printed includes a mirror located immediately behind the transparent or translucent printing material as it leaves the machine, so that the projection beam passes through the paper and is reflected back therethrough to the projection lens. As shown, the mirror 17 is curved at its lower end and is located adjacent the printing platen 13, the paper passing vertically after printing and being held in contact with the mirror by guides 18. Lamps 19, reflectors 21, 24 and projection lens 23 comprise the projection system. The mirror 17 may be in other positions than the vertical. To ensure projection only when the paper is stationary, the lamps may be switched out or dimmed or a mechanical shutter associated with the lens.
